A week after the wall was complete, I noticed that the bricks on top were all uneven. The subcontractor is nowhere to be found.

Is there an easier way for me to fix or hide them other than removing each one and resetting it? This wall is 52 ft across. Can I hide it with beveled bricks? Is it better to just remove each one and do it all over again? Thanks, all suggestions are appreciated. Someone suggested hiding it with plants but I really want to appreciate the brickwork instead.
